GLM 5.3 SlopCodeBench Results

Howdy once again, I had a request to try out 5.3 on the benchmarks - they're unsaturated so it's a fun test right now! This one was interesting because I accidentally ran it on all 36 problems (rip $200) instead of the 9 i typically do previous runs a b c benchmark context: the ai is tasked to build a tool step by step, we add new requirements mid way - it has to handle new things without breaking the old things - the benchmark "hides" the old tests So it didn't magically solve the benchmark just like all the other AIs, i don't think there has been a single successful solve yet, but it did tie with Fable/Sol in the same subset of problems! Another interesting thing that we expect is that the more difficult the problem, the more $$$ it gets - so difficulty seems to be correlated with token output in order to solve them AI;DR full results On the three-problem, 17-checkpoint list from the Opus 5 report, GLM scored 8/17 strict (47.1%). On the six-problem, 30-checkpoint list from the Fable, Sol, and Kimi report, it scored 10/30 (33.3%), tied at the strict threshold with Fable 5 and GPT-5.6 Sol.
